How to give a chemical push to ammonia in a compression ignition engine?

Anne-Gaëlle Morin

The initial work on direct additivation to ammonia in a Rapid Compression machine showed promising results and radical ignition delays and temperature reduction. From these tests on, tests conducted on a research mono-cylinder engine, with the help of the Prisme laboratory at the University of Orléans, demonstrated that the additive used in pilot fuels allowed for better controlled ignition than the pilot fuel alone, better and eased cycle to cycle stabilization and better power output. It also quite dramatically reduced the amount of pilot fuel needed. It seems that the additive helps to keep ammonia in the combustion event even…

Liebherr: ammonia fuel for the mining sector

Julian Atchison October 07, 2024

Liebherr and Italy-based Bruno Generators will embark on a joint development project exploring ammonia fuel for off-grid power generation in the mining sector. Building off “promising” results in Liebherr’s own internal trials with ammonia fuel, future applications could include power for heavy vehicles like electric excavators.

Wärtsilä ammonia engine to power the Viking Energy

Julian Atchison August 30, 2024

Wärtsilä has been contracted to supply the total technology package for the conversion of the Viking Energy to run on ammonia fuel. The original plan to retrofit the vessel with a 2 MW solid oxide fuel cell system was delayed by supply chain and development challenges, but SOFC developer Alma Clean Power will continue to test and scale its direct ammonia-fed technology for maritime applications.

R&D recap: the Journal of Ammonia Energy – volume II

Geofrey Njovu August 13, 2024

Ahead of the international Symposium on Ammonia Energy event next month, we recap R&D presented in the second edition of the Journal on Ammonia Energy:

  • An integrated, indirect ammonia solid-oxide cell featuring a heat exchanger and ammonia cracker was modelled, built and tested by the UK’s Science and Technologies Council (STFC).
  • The techno-economics of the transportation of energy from Orkney, Scotland to Milford Haven, Wales using ammonia as an energy carrier transported by ship may be the most cost-effective option.
  • N2O and NOX conversion in ammonia engine exhausts is limited by the presence of oxygen and water, presenting an optimisation challenge for technology developers.
  • And an academic-industry joint session on ammonia safety highlighted multiple projects currently underway to tackle the risks associated with the use of ammonia in new commercial sectors.
